Cooling And Power Supply - Moravian Instruments G2 Series Mark II User Manual

Cooling and power supply

Regulated thermoelectric cooling is capable to cool the CCD chip up to
50 °C below ambient temperature. The Peltier hot side is cooled by fan.
The CCD chip temperature is regulated with ±0.1 °C precision. High
temperature drop and precision regulation ensure very low dark current
for long exposures and allow proper image calibration.
The camera head contains two temperature sensors – the first sensor
measures directly the temperature of the CCD chip. The second one
measures the temperature inside the camera shell.

The cooling performance depends on the environmental conditions and
also on the power supply. If the power supply voltage drops below 12 V,
the maximum temperature drop is lower.
